Abstract

PURPOSE:To eliminate the waste of illumination light, by joining a glass cylinder to the emission end surface of a light guide to give a flection to the illumination light and then illuminate an object to be observed and at the same time securing an image formation of the above-mentioned object on the incident end surface of an image fiber. CONSTITUTION:A glass cylinder 16 that transmits the illumination light of a light guide 12 is joined to the emission end surface 15 of the guide 12 which is provided at the outer circumference of the incident surface 18 of an image fiber 11 via a jacket part 13 and with its outer side surrounded by a jacket part 14. A convex lens 19 is put in front of the cylinder 16 to give a flection to the illumination light for an effective illumination of an object 17 to be observed and to secure an image formation of the object 17 on the surface 18. In such way, an inconvenience in which the object 17 is illuminated only in a circular form as long as no lens is used can be eliminated. Thus the waste of illumination light is avoided to ensure a suited application to a medical endoscope or the like.
